I have a new (cleaner) photo now that the PRS SIlver Sky has been in production for a while and the production units are out in the wild. It turns out that the resistor value has changed to 3.3MOhm and that is largely the difference between the prototype and production. This will make the guitar slightly "brighter" than the prototype 2.7MOhms but since the pots could swing at least 10% in value, it really will be slightly different between guitars. Nature of the beast. I recommend Fender Fat 60's pickups as it's the closest tone to Silver Sky pickups off-the-shelf.
